Bitcoin’s ascent to its all-time excessive unfolded in opposition to a really uncommon backdrop: steadily compressing volatility. Whereas most markets are likely to exhibit rising implied volatility as costs push larger, Bitcoin has performed the other, particularly in latest months.
This habits is completely captured by the Bitcoin Volatility Index (BVIV), a metric that tracks the implied volatility of Bitcoin over a hard and fast horizon based mostly on choices pricing.
BVIV is derived from the implied volatility floor of Deribit’s BTC choices. Particularly, it calculates a time-weighted common of the 30-day implied volatility throughout a variety of out-of-the-money places and calls, adjusted for liquidity and skew.
Functionally, BVIV serves as Bitcoin’s model of the VIX: a real-time measure of anticipated volatility over the approaching month. A better BVIV studying implies that the market anticipates bigger worth swings, whereas a decrease studying displays expectations of calm.
Since September 2022, BVIV has ranged from a excessive of 96.6 through the FTX collapse to a low of 36.3, first recorded in August 2023 and just lately matched in late July 2025. The total-sample correlation between BVIV and Bitcoin’s worth is barely unfavorable at -0.13, which means implied volatility has tended to ease considerably as the worth climbs.
Nonetheless, that relationship has turn into materially stronger in latest months: the 12-week rolling correlation between BVIV and BTC worth reached -0.45 in early June 2025 and has remained in that vary by way of early August.
The shift is notable as a result of it factors to structural adjustments in how volatility is priced. Traditionally, speedy BTC rallies, like these seen in 2017 and 2021, typically got here with increasing volatility as merchants piled into upside calls and hedgers paid up for defense.
In distinction, the present atmosphere contains a mature choices market, deeper liquidity, and a surge in short-volatility methods throughout institutional desks. This structural change has allowed BTC to rise sharply with out triggering a corresponding spike in implied volatility.
Latest information additional confirms this disconnect. Through the week ending August 4, Bitcoin closed at $115,050.91, having ranged between $109,200 and $121,000 over the earlier 5 weeks. On the identical time, the BVIV fell to 36.3, simply 0.01 beneath its all-time low. Realized volatility over the previous month stands at roughly 24%, placing the implied-realized unfold at 12 proportion factors, among the many widest of the previous two years.
This setup has vital implications. First, it suggests a market that’s aggressively brief volatility. Sellers and structured product desks are more and more comfy promoting premium, assuming the BTC market will stay range-bound or development gently upward.
The slim spreads and flat time period construction replicate a perception that no main directional catalyst is imminent. Second, the funds that depend on volatility inputs to dimension publicity can now maintain extra BTC per unit of danger. This introduces a self-reinforcing suggestions loop: as implied vol compresses, systematic flows improve, additional stabilizing the market till a shock happens.
There’s additionally a tactical interpretation. When implied volatility hits document lows whereas worth hovers close to all-time highs, historic precedent suggests an elevated chance of abrupt reversal or breakout. Prior BVIV troughs (like these in August 2023 and February 2024), have been adopted inside two to 3 months by spikes above 55 and spot strikes exceeding 18% in both path.
This isn’t a prediction of reversal, however slightly a warning that the choices market is at present pricing in far much less motion than has sometimes occurred following such circumstances.

With volatility low and directional conviction excessive, choices are low-cost relative to realized worth swings. This creates alternatives for these searching for to build up lengthy publicity to volatility itself, significantly by way of longer-dated name spreads, strangles, or calendar constructions. The present setup presents constant carry for market makers however elevates the chance of a gamma squeeze if flows immediately reverse.
The rising image is one in every of a maturing, however doubtlessly overconfident, market. Bitcoin’s skill to drift above $110,000 with out sparking a bounce in BVIV displays improved liquidity, deeper institutional participation, and extra refined volatility promoting.
However historical past means that such intervals are finite. Whether or not by way of a regulatory shock, macro shock, or sudden sell-off, the subsequent growth in volatility is more likely to be sharp as a result of the premium at present being collected for taking that danger is vanishingly small.
For now, the volatility ground has held. But when the previous is any information, compression this excessive hardly ever persists for lengthy.
